The Cascade Range is an arc of volcanoes that extends from southwestern British Columbia to northern California. One of the six major composite volcanoes (formed by alternating layers of extruded lava and compacted ash) is Mount Baker in northern Washington. Close to the Canadian border, Mount Baker is about 85 miles north-northeast of Seattle and 65 miles southeast of Vancouver, British Columbia. This beautiful, snow-capped peak dominates the skyline from Bellingham, Washington to Vancouver, an...

[image]William Smith's Geological Map of England: Image of the Day - NASA -- NASA Image Of The Day
Before the late eighteenth century, residents of England didn't necessarily take much interest in the rocks under their feet. The arrival of the Industrial Revolution, however, drew the attention of the country's entrepreneurs downward. England's industrialists began plunging deep underground for coal -- the fossilized remains of ancient swamps -- and carving canals across the countryside to transport it efficiently...

In the western United States, water is the most critical natural resource. In addition to drinking supplies, water sustains agriculture, provides hydroelectric power, and nourishes ecosystems. The artificial Lake Powell and Lake Mead reservoirs on the Colorado River are the most important water caches in the West. Over the past several years, sustained drought has brought these reservoirs to unusually low levels, though not down to the record lows of the 1950s...

[image]Dark Dune Fields of Proctor Crater, Mars - NASA
The dark rippled dunes of Mars' Proctor Crater likely formed more recently than the lighter rock forms they appear to cover, and are thought to slowly shift in response to pervasive winds. The dunes arise from a complex relationship between the sandy surface and high winds on Mars. Similar dunes were first seen in Proctor Crater by Mariner 9 more than 35 years ago. This image was taken by HiRISE camera on board the Mars Reconnaissance Orbiter, currently in orbit around Mars...

Taken in 1989 by Voyager 2 during its flyby of the Neptune system, this is a global color mosaic of Triton. The color was synthesized by combining high-resolution images taken through orange, violet and ultraviolet filters; these images were displayed as red, green, and blue images and combined to create this color version. With a radius about 22 percent smaller than Earth's moon, Triton is the largest satellite of Neptune and is one of the few bodies in the solar system known to have a nitrogen...

Many scientists regard receding glaciers as a symptom of global climate change. While certain types of glaciers -- such as surge glaciers and tidewater glaciers -- are actually expanding, there are many areas where scientists report glaciers are wasting away and that climate change is the culprit. For instance, 150 years ago there were 147 glaciers in Glacier National Park. Today, only 37 glaciers remain, and scientists say they will likely completely melt by the year 2030...

[image]Tropical Storm Alberto: Image of the Day - NASA -- Images produced by Hal Pierce (SSAI/NASA GSFC) and caption by Steve Lang (SSAI/NASA GSFC).
Alberto began as a tropical depression on the morning of June 10, 2006, having formed from an area of low air pressure over the northwestern Caribbean Sea. This depression moved generally northwestward through the Yucatan Channel between western Cuba and the Yucatan Peninsula and into the south-central Gulf of Mexico. The system was rather poorly organized as a result of southwesterly wind shear. This shear pulled the weather system from the rounded shape of a typical tropical storm and gave Alb...

Scientists have yet to discover what caused the strange spiral structure. Nor do they know why it glows. The glow may be caused by light reflected from nearby stars. As for the spiral itself, current supposition is that this is the result of a star in a binary star system entering the planetary nebula phase, when its outer atmosphere is ejected. Given the expansion rate of the spiral gas, a new layer must appear about every 800 years, a close match to the time it takes for the two stars to orbit...

[image]Lakes Drain under Antarctic Ice Sheet: Image of the Day - NASA -- Images courtesy Ted Scambos, National Snow and Ice Data Center
Throughout Antarctica, broad ribbons of ice known as ice streams shed large quantities of ice into the ocean. Glaciologists try to closely monitor ice streams because their movement ultimately affects sea level. Figuring out Antarctic ice stream behavior is tricky, however, and not just because this continent is so remote. Water influences ice stream flow, but the water lies thousands of feet below the ice surface...

[image]Wildfires in Glacier National Park and Alberta: Image of the Day - NASA -- Image courtesy Jacques Descloitres, rapidfire.sci.gsfc.nasa.gov/ MODIS Land Rapid Response Team at NASA GSFC
Fast-moving forest fires continued to race through terrain at the front range of the Rocky Mountains in northern Montana (bottom right) and Alberta, Canada (top right), on July 27, 2003. In Montana, the fires (marked in red) forced thousands of tourists and staff to evacuate Glacier National Park (image center) late last week, while in Canada, the blaze forced many residents of the small community of Hillcrest to evacuate their homes on Sunday...

[image]The Nile : Image of the Day - NASA -- Image credit: NASA/GSFC/JPL, www-misr.jpl.nasa.gov/ MISR Team.
This image of the northern portion of the Nile River was captured by the Multi-angle Imaging Spectroradiometer's (MISR's) nadir camera on January 30, 2001. The Nile is the longest river in the world, extending for about 6700 kilometers from its headwaters in the highlands of eastern Africa. At the apex of the fertile Nile River Delta is the Egyptian capital city of Cairo. To the west are the Great Pyramids of Giza...

This 10.5 by 11 km area in northern Chile was acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on April 7, 2000. Dramatically displayed is a geological angular unconformity: a contact between layers of rock at different angles. On the right side of the image, Cretaceous sediments (146 to 65 million years old) were tilted upward to an angle of about 50 degrees, then eroded...

[image]Den Helder, Netherlands: Image of the Day - NASA -- The featured astronaut photograph eol.jsc.nasa.gov/scripts/sseop/photo.pl?mission=ISS015&roll=E&frame=5977 ISS015-E-5977 was acquired May 1, 2007, with a Kodak 760C digital camera using an 800 mm lens, and is provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Laboratory, Johnson Space Center. The image in this article has been cropped and enhanced to improve contrast. The spaceflight.nasa.gov/home/index.html International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC eol.jsc.nasa.gov/ Gateway to Astronaut Photography of Earth.
The city and harbor of Den Helder in the northern Netherlands has been the home port of the Dutch Royal Navy for over 175 years. The location provides access to the North Sea, which has made it an important commercial and strategic port. Bright red agricultural fields to the south of Den Helder indicate another noteworthy aspect of the region -- commercial farming of tulips and hyacinth. This astronaut photograph is an oblique view (an angled, not a ''straight down''view) of the Den Helder regio...
